Description
Verfahren zur Herstellung eines Rostschutzanstriches. Alle bisher bekannten Rostschutzfarben weisen mehr oder weniger Mängel auf.Process for the production of a rust protection paint. All so far known anti-rust paints have more or less defects.
Durch langjährige Versuche und Untersuchungen der Farbpigmente ist es nun gelungen, die Ursache dieser Mängel zu beseitigen.Through many years of trials and studies of the color pigments is has now succeeded in eliminating the cause of these deficiencies.
Die Hauptbedingung für eine Rostschutzfarbe ist die, daß ihre Grundstoffe selbst von den Atmosphärilien nicht angegriffen werden. Diese Bedingung wird jedoch bisher von keinem Produkt des Farbmarktes absolut erfüllt.The main condition for an anti-rust paint is that its raw materials are not attacked even by the atmospheric lilies. However, this condition will so far absolutely not fulfilled by any product in the color market.
Vorliegendes Verfahren beseitigt nun alle etwa in den Grundstoffen. vorhandenen, in Säuren leicht löslichen Bestandteile durch Extrahieren. Es werden dadurch der Schwefel- und schwefligen Säure .sowie dem Ammoniak, dem schwefelsauren Ammon und dem Schwefelwasserstoff der Atmosphäre alle Angriffsmöglichkeiten genommen.The present process now eliminates all of the raw materials, for example. existing, easily soluble in acids by extraction. It will thereby the sulphurous and sulphurous acids, as well as ammonia, the sulphuric acid Ammon and the hydrogen sulphide in the atmosphere have taken away all possibilities of attack.
Die Grundstoffe (z. B. Cyprische Umbra, Rebschwarz, Spinell, Graphit, Magnoferrit, Chromgrün, Krongelb und noch viele andere) werden auf das feinste in einem Kollergang gepulvert, durch ein Sieb getrieben und nun unter Bewegung durch ein Rührwerk in. einem verzinnten Kessel mit verdünnten Mineralsäuren (H Cl Hz S04 -[- H N O$) .behandelt. Ist die Hauptmenge der Beimengungen gelöst, wird abgehebert, auf Filterpressen gebracht, mit etwas stärkerer Säure so lange nachgewaschen, bis auf Platinblech kein Rückstand mehr verbleibt, ein Zeichen, daß nichts mehr in Lösung geht. Dann wird mit erwärmtem Wasser weiter ausgewaschen, bis die Säurereaktion verschwunden ist. Die abgesaugte Masse wird nun bei zo5° C getrocknet und in der Farbmühle wie gewöhnlich weiter verarbeitet.The basic materials (e.g. cypric umber, black vine, spinel, graphite, Magnoferrite, chrome green, crown yellow and many others) are in the finest in Powdered in a pan mill, driven through a sieve and now through with movement a stirrer in a tin-plated kettle with dilute mineral acids (H Cl Hz S04 - [- H N O $). Treated. Once the main amount of the admixtures has dissolved, it is siphoned off, put on filter presses, washed with a little stronger acid until no residue remains on the platinum sheet, a sign that nothing is in solution goes. Then it is washed further with heated water until the acid reaction disappeared. The extracted mass is now dried at zo5 ° C and placed in the Color mill processed as usual.
Als Bindemittel ist guter Leinölfirnis, am besten Mangan- oder Chrom-Leinölfirnis zu verwenden.A good binding agent is a good linseed oil varnish, preferably manganese or chrome linseed oil varnish to use.
Es ist bekannt, bei der Herstellung von Rostschutzanstrichmassen Holzkohle zu verwenden, von der bestimmte Sorten wenig oder gar keine säurelöslichen Bestandteile enthaltem.It is known to use charcoal in the manufacture of anti-rust paints to use little or no acid-soluble components of the certain varieties contain.
Die Wirkung der Holzkohle beruht aber darauf, daß sie durch Absorption des *Sauerstoffes das Eisen rostfrei erhält, da es in Holzkohle eingebettet ist.The effect of the charcoal is based on the fact that it is absorbed by it des * oxygen keeps iron rust-free because it is embedded in charcoal.
Im Gegensatz hierzu kommt es bei dem vorliegenden Verfahren auf die Erkenntnis an, daß wirklich tadellose Rostschutzanstriche nur erhalten werden, wenn bestimmte Bestandteile der Grundstoffe durch Behandlung mit verdünnten Mineralsäuren entfernt werden. Eine Absorption. des Sauerstoffes kommt nicht in Betracht, da die meisten Grundstoffe sich gegen Sauerstoff indifferent verhalten.In contrast to this, the present method relies on the Recognition that really impeccable anti-rust coatings can only be obtained if certain constituents of the raw materials by treatment with diluted mineral acids removed. An absorption. of oxygen is out of the question, since the Most basic substances are indifferent to oxygen.
